The c.623C>T (p.A208V) alteration is located in exon 4 (coding exon 3) of the SERTAD4 gene. This alteration results from a C to T substitution at nucleotide position 623, causing the alanine (A) at amino acid position 208 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
